On Travel tripods: Comparing 5 aluminum kits article (97 comments in total)
In reply to:

Artak Hambarian: Very welcome review, since it tries to make a measurable comparison, finally. I have read also a German article on a similar comparison of Feisol, Manfrotto and Gitzo Tripods through a laser pointer mounted on the tripod. I would like to suggest to share more details, so that anyone could make a similar comparison:
1. Shape of the aluminum block and the way it and the ipad are mounted.
2. data on solenoid hammer - power rating, core weight, voltage, etc.
3. Where exactly the vibration is applied - mm-s from the ground.
4. Name the seismometer app used.
5. Try spikes, extend column, etc. A photograph of the setup is very very welcome.
In fact DPReview can end the "endless" and meaningless increase of the weight rating by manufacturers by setting standards for tests!

Mark, thank you very much for explanation. I wish DPReview leads the standardisation process. I still have questions, e.g. related to the 60lbs valve (! - are you sure? You in fact can easily break Al legs with that weight. Probably that's why column up yields too much of vibration). I am sure next articles will be read with as much or more of interest!

...Certainly another good source of vibration is the slap of the mirror or the shutter vibration. Then no need in solenoid. However, possibly the seismometer app/ipad combo may not have the needed sensitivity. Interesting...

On Quick Review: That Steady Thing article (65 comments in total)

Excuse me for multiple posts - I just could not see if the post went through on my Android device. Now I cannot find how to delete my erratic posts...

Look at the Novoflex tripod/quadropod solutions - this is the most modular support system. It has similar solutions but more expensive I guess.

Markol: I sometimes see people using tablets for taking photos, so I guess that's the connection to this article being posted on the dpr site. Otherwise I would think that it's slowly turning into a tech-blog.

I cannot believe that you watch your or any photos after only printing... or... do you?

On Flashpoint Budget Studio Monolight Review article (41 comments in total)
In reply to:

michael_alabama: 300 "Ws" and 160 "Ws" is not sigificantly longer to write than "W". "Ws" is the energy of the Flash. The Power "W" is much higher than 300 W. Why not write the correct dimension? You can take it from the Adorama description. Perhaps they have the time to write the longish dimension?

Correct. But the Ws is the convention.

On Leica M Monochrom now available in grayscale (sort of) article (137 comments in total)
In reply to:

RichRMA: Be nice if DPreview tested one of these, I'd like to see how a monochrome sensor presents noise.

...just the same as any other recent dslr - maybe x.xx% better, not more than 10%...

On Light Field Cameras - Focusing on the Future article (133 comments in total)

Nice! In the future, no doubt only this type of cameras shall survive - if you do not believe, look even into further future - plain cameras shall be used only for a few special cases. However I will wait for its Foveon type a realisation and @ 36MP or higher resolution I hope it will not take too many decades!

Valiant Thor: Colorful but highly exaggerated title. The deepest men have ventured into the earth is around 2.4 miles which would be 0.00057 % to the center. It may be a while before someone claims that prize.

...without the percent sign...

In reply to:

Artak Hambarian: While have not used this bag, one drawback is evident: you need to put it on the ground - read mud, water, steep slope, ice - to change a lens. The art of bag making still needs to say its word in combining comfort, performance, speed and versatility, in my opinion...

I mean its better not to put anywhere, especially when there is no place to put. This is why my bag for the last few years is the Lowepro Flipside 400. however its just a ted bit smaller than I need. There a bigger one too but I yet do not hurry with it. The Flipside series allows turning the backpack to your front and work with it without putting on the ground. The 400 is not without drawbacks either, but so far has been the best for me when climbing the glaciers.

Guys they have proven tge concept. I personally will be rather satisfied if it charges in 300 seconds, i.e. 5 minutes. Thats an excellent result too and will keep the charger reasonably small.

On Integrating the MacBook Air into a pro workflow article (353 comments in total)
In reply to:

AliRoust: The problem with this laptop is that it is 8 bit only so you can't ever see 10 bit color
In order for one to be able to see 10 bit color one needs to have the following chain of elements. If any of these elements is missing it won't work:
1) A camera that can capture RAW images ( Jpegs are 8 bit and won't work). Most quality cameras offer RAW as an option even some cell phones like Nokia 1020 now also do.
2) An operating system that supports 10 bit images. Mac os X does not, Windows does!! Even older version of windows do.
3) Appropriate software such as Photoshop or Lightroom
4) A video card that can output 10 bit signal such as Nvidia Quatro or AMD Firepro lines. The Nvidia GeForce Gt on this one does not.
5) An LCD that can display 10 bit color. This one does not. No Apple LCD does.

In other words even if you purchase a second monitor to attach to any Apple product you will not be able to ever see high quality 10 bit images.

Thank you! I will check if my 30" hp is 10 bit.

On Integrating the MacBook Air into a pro workflow article (353 comments in total)
In reply to:

DonThomaso: A very good alternative if you don't want a MacBook Air is the Sony Vaio Pro 11/13-range. I recently bought a 11-inch (a nice Panasonic IPS 1920x1080 display) with 8 GB RAM and 256 GB SSD for €850. Best of all - magnesium body and weighing in at 0,87 kg! That's portable! I do most of my work on a desktop, else I would have considered the 13-inch.

DonThomaso, is it 10 bit, or 8 bit like the Air?

AliRoust, can you rcommend a 10 bit, i7, USB3 1920X1080 or higher notebook? 13" seems reasonable to mee too... is it easy to search for 10 bit ready notebooks?
